IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 213,024, dated March 4,1879; application filed September 20, 1878.

To all whom it may concern:

Be it known that '1, JOHN H. YAGER, of Jacksonborough, in the county ofButler and State of Ohio, have invented a new and Improved Harrow, ofwhich the following is a specification In the accompanying drawings,Figure 1 represents a top view of my improved harrow Fig. 2, a rear viewof the same; Fig. 3, a top view of the harrow with the sections arrangedat an angle of inclination to the center; and Fig. 4 is a side view ofthe same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish for farming purposes animproved harrow the sections of which may be adjusted at any angle tothe central axis and convenientlycarried to and from the fields; and theinvention consists of two centrally-hinged harrowsections, which aremade of toothed pieces that are pivoted to cross-bars, and adjusted atany suitable angle of inclination to the ion gitudinal axis by means ofinterlocking ratch ets and clamp-screws of the cross bars and pieces.

The harrow-sections are jointed by hingestraps of different length. Thehandles are applied to the barrow-sections by lockingratchets andclamp-screws, and maybe locked into position below the barrow-sectionsto serve as runners.

Referring to the drawings, A. A are two harrow-sections, which areconnected by a central hinge-joint composed of rod 0 and hinged strapsC, so as to fold one on the top of the other. Each harrow-sectionA ismade in the customary manner of toothed pieces B, which are connected bypivot-bolts a to metallic cross-straps G. The cross-straps are firmlyattached to the hinged straps C, of which the two front straps areshorter than the rear straps for the purpose of admitting the connectionof the barrow-sections when adjusted symmetrically at an angle to thelongitudinal axis, as shown in Fig. 3. The crossstraps O are bent up attheir middle portions, and interlocking ratchet-wheels D, with radialteeth, interposed between the straps and the pivoted pieces B.

Through the straps, ratchets, and toothed pieces pass clamp-screws I),which, when loosened, disengage the ratchets, so that the pivoted piecesB may be set to any angle with the cross-straps.

By tightening the clamp screws 1), the toothed pieces are rigidly lockedin the desired position, either at right angles or any other angle tothe cross-straps.

The outermost toothed pieces B may be detached when it is desired tomake the harrow smaller, as when changed to assume an angle ofinclination to the center axis, as in Fig. 3. The outer pieces B areattached by separate straps O and by diagonal braces 0 so as to befirmly connected to the harrowsections.

The handles Eare attached by means of interlocking ratchets E andclamp-screws d to the rear ends of the pieces B. The harrowsections arecontrolled by the handles, which are then rigidly clamped in raisedposition thereto, as indicated in dotted lines in Fig. 4. By applyingboth harrows to one barrow-section, swinging the handles below theharrowsections, so that the eyes 0 of the bent-down rear ends engageteeth of the pieces B, and finally locking the handles firmly in thisposition by the ratchets and clampscrews, the handles serve as runnersto convey both sections, one folded upon the other, to and from theplace of work.

To the front part of the harrow-sections are 1. The harrow hereindescribed, consisting, ably secured to the rear ends of the toothedessentially, of the hinged sections A A, combars B of one section of ahinged harrow by posed of toothed bars B, cross-straps O, interlockingravtehets D, substantially as and hinged straps rod 0*, and interlockingfor the purpose described.
